 Dolichos tetragonolobus L.
Ecology and distribution
Trop. Afr.
Biology : Annual or perennial glabrous climbing herb to 3-4 m long, with a tuberous root; leaflets 3, triangular; flowers large, mauve, or mixtures of mauve, cream, blue, yellow-green or red, or occasionally white, 2-10 in (long-) pedunculate racemes;
Ecology : Known only in cultivation, with an estimated 1500-3000 vars. world-wide. Highest genetic diversity in Papua New Guinea, and also in Indonesia. Origin of domestication uncertain.
  Most widely cultivated in Asia: Burma, Papua Guinea, Indonesia. Also in West Indies, N S. America, Australia; in W and SE Africa. - An exceptional vegetable crop in providing a food source at all stages of its life cycle, and all parts edible.
  Similar to P. grandiflorus but larger in all parts. Perhaps a result of selection through domestication. Recent discovery of a host-specific fungus on P. grandiflorus in Zaire, also infecting the winged bean suggest a relationship [see more in the book]
